Welcome to Cisco Support Community. We would love to have your feedback.
Does Callmanager have a feature to block malicious calls,based on the calling number? If the answer is yes, how can I do the settings?
Yes, CCM has this feature, take a look to the following document:
Correct, this feature flags teh call in the call detail record database and instructs the gateway to send a message to the public switched telephone network, allowing the service provider to take appropriate action. MCID is supported only on NET5 switches and must be enabled by the service provider.
it's not easy, but i did it, even though I was informed it was not possible. you can't do it from callmanager, you have to involve your gateway/router.
1. create a translation-rule for matching patterns (the number you want to block)
2. create a translation-profile and add the rule(s) to it.
3. assign the translation-profile to the dial-peer for all your incoming calls.
I guess it does depend on what router you use as to how the commands go, i use a 3825. if you have trouble figuring it out, i can try to lay out some commands for you.
Here you are actually doing it on the Gateway (H323 Gateway specifically). This has always been possible. But having CallManager based on the Calling Number, is not possible as of now.
Thank you so much!Guys.Doing this by H323 Gateway is acceptable.Could you pls give me a configuration example? It will help me have a better understanding.
voice translation-rule 1
rule 1 reject /##########/
rule 2 reject /##########/
*where #s is the numbers or patterns you're blocking
voice translation-profile call_block
translate incoming 1 (the 1 references the collection of translation-rules)
here conigure your incoming call dial-peer
dial-peer voice 1 voip (check the running-config if you're not sure what yours is)
call-block translation-profile incoming call_block
that should be it, let me know if you run into any snags.
